Hello Ned! There were more female tanks at the start but they were soon converted to male.... so I have read in a book. I have the Tankograd book Sturmpanzer A7V and found it very helpful in understanding the different types and manufacturers. There is explained how the Germans planned more female tanks than male tanks (1 male to 4 female) but soon found out that they needed more firepower and so converted the female tanks to male tanks. Only number 501 (Gretchen) was to see combat as a female tank. One of those things you can read in the book is that due to distortion of the armourplates that came from Krupp that there were A7V's with the sides in five plates in stead of one big side-armourplate for the Röchling tanks.

So if you can get one of the books ...... buy it Tankograd world war one, Sturmpanzer A7V No. 1001.
